It made a difference in that I didn't have to run a ton of preload. It just didn't absorb shocks so much as transmit them directly to my backside. It was a very heavy spring and was chosen based on price (cheap, used) rather than some scientific process.

Further to this discussion - I obtained a clevis mount from Forsaken Motorsports in Canada. Its intended to adapt an Ohlins shock to a BMW 1000RR (pics below). Cost $80. Beautiful item.

Its a long clevis, so when fitted the eye to eye length of my Ohlins shock (see previous posts) goes from about 305 mm to 335 mm, with clevis fully wound in. I note that this about 17 mm longer than the stock GRiSO shock. Would this be too big a jump in ride height?

Haven't fitted it to the bike yet - waiting for a 36/105 spring to arrive later in the week. It will need spacers as the inside width of the clevis is 5 mm larger than on the original, as per the Ohlins clevis.

Stock GRiSO shock should be approx 320mm. Increase it by 15mm ...... with a rocker ratio of 3:1 = 45mm increase in rear ride height ....... excellent for ground clearance and quick steering.

In round figures that will reduce your rake by approx 1.5 degrees

DON'T DROP YOUR FORKS TO THE 6TH RING!

Not unless you want a 22.5 degree rake with reduced trail.
Hope you got long legs.

Thanks Ghezzi - that's good to know & great advice. Fortunately I'm not vertically challenged so the increase in ride height won't be a problem. I'll report back once I get it on the bike. Can't wait...

I started with my Bellagio at 28* rake. Yours is 24.5*

I Raised the rear 60mm and dropped the front 30mm which netted me approx 3.4 degree reduction in rake. (now 24.6*)
However I did it in stages, plotting the numbers as I went.

My reason for fitting a Multistrada front end was the Ducati triple clamps have 29mm less offset, thus adding to my trail which had dropped to 77mm.
Another bonus, all these mods reduced my wheelbase by 50mm.

I'm saying be careful, be very careful. If you don't know the numbers, or worse, if you don't understand the ramifications of the wrong set of numbers, somebody could get hurt.

Thanks - I appreciate what you are saying, based on your extensive experience. I will evaluate it cautiously and most certainly won't be backing off the front preload. Cheers.

Mind you, Ghezzi made this statement in an earlier post:

".... had a few head knocks along the way. Last count was fall down go boom 26 times."

Sounds like he's got at least a little experience.

Waterbottle,

Tell us about the Ohlins clevis pin you used, was it the long or short clevis you used ?

What spacers did you have to make up ?

Nobleswood, I can take some pics and get back to you tomorrow. Basically just washers were used as spacers, and a couple of tricks too . Later, beer drinking in progress .......
